Its 276 × 175 × 190 mm and the positive terminal on the right make it the exact replacement for the 51 Ah battery fitted as standard to many scrubbers and sweepers. - Direct replacement for the machine's original battery. - No maintenance, no water top-ups. - Resistant to deep discharges and daily recharging. - GEL: excellent resistance to deep discharge and long cycle life. ### What the Q-Battery 12GEL-51 is for The Q-Battery 12GEL-51 is designed for scrubber-dryers, sweepers and industrial cleaning machines: full working shifts with deep discharges and daily recharging. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 24 kg, A-Pole terminals and B13 hold-down. ### The Q-Battery 12GEL-51: GEL Traction Battery range and GEL technology The 12GEL-51 is part of the Q-Battery **GEL Traction Battery** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family. In a GEL battery the electrolyte is gelled with silica: it is fully sealed, cannot spill and tolerates deep discharge very well. It is the preferred technology in electric mobility, marine service and heavy-cycling applications. ### Will it fit your current battery tray? In terms of format, the Q-Battery 12GEL-51 measures 276 × 175 × 190 mm (length × width × height) and weighs 24 kg. The positive terminal on the right decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. It uses a B13 hold-down and A-Pole terminals, the system that anchors and connects it in the vehicle. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters. ### What Q-Battery does differently Q-Battery specialises in AGM and GEL VRLA batteries for UPS, telecoms, solar and deep cycling, with long-life and tubular-plate series for industrial use. All the Q-Battery batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### How to make it last longer Recharge the machine at the end of each shift and avoid repeated full discharges. GEL batteries need lower charging voltages: always use a charger with a GEL mode so as not to damage the electrolyte. ### Official warranty The Q-Battery 12GEL-51 comes with the **manufacturer's official warranty** against manufacturing defects. If it fails through a defect within the warranty period, we replace it at no cost to you. ### Delivery times and returns Same-day dispatch from our warehouse for in-stock orders placed **before 6:00 pm**: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for **14 days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email. ## Frequently asked questions ### Is the 12GEL-51 model a gel battery? Where is it used? Yes. The Q-battery 12GEL-51 is GEL: sealed lead-acid in which the electrolyte is a gel. Its maximum charge voltage is lower than an AGM's, so a GEL-specific smart charger is needed. Designed for cyclic use (solar installations, motorhomes, electric wheelchairs, motorcycles), it tolerates deep discharges very well. ### What are the dimensions of the Q-battery 12GEL-51 battery? Check the room available in your device, because a single millimetre too much can stop the clamp from closing. Its dimensions are 276×175×190 mm, also written 276x175x190 mm; the height already includes the terminals. In European terms it is a L3 case. ### On which side is the positive of the 12GEL-51 model? Polarity of the Q-battery 12GEL-51: positive on the right. Seen from the front, terminals towards you, the positive (+) is the post with the red ring. Compare it with the battery you are replacing: if it does not match, cables must be lengthened or the system reconfigured, with a risk of short circuit. ### Q-battery BATTERY-12GEL-51 or Sonnenschein GF12050V: which one to choose? It has the same dimensions, voltage and technology as the BATTERY-12GEL-51, although it is not a manufacturer-approved equivalent. Compared with the BATTERY-12GEL-51 it has 4 Ah more. It costs 70,50 € less. Check the positive terminal side and the original capacity before ordering; otherwise it is a straight swap. ### Q-battery BATTERY-12GEL-51 or Sonnenschein GF12050VG: which one to choose? Same case and same technology as the BATTERY-12GEL-51: an alternative by size, not an official equivalent. Compared with the BATTERY-12GEL-51 it has 4 Ah more. It costs 65,90 € less. If the polarity matches and your equipment had a similar capacity, it works as a replacement; if in doubt, ask us with your model. ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2012. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-11-08*
